In the universe energy, matter and go as per quantum. Energy is
released in quantum of photon. Electron has a quantum mass. Proton
has quantum mass. Both has a quantum charge. Neutron has a quantum
mass. Speed of light is a quantum. Big bang is a quantum event
essentially occurring at particular mass. It takes a quantum energy
for shifting of electrons from one shell to other. In
photo-luminescence light energy is released in quantum.
